| 1 | 塔里木盆地和田河气田轻质油成熟度判定及其油源意义显示文摘为评价和田河气田轻质原油的成熟度,利用气相色谱与气相色谱-质谱联用仪,对和田河气田4个轻质原油中具有成熟度信息的化合物进行分析。轻烃庚烷值与异庚烷值、甲基双金刚烷参数、甲基菲参数、甲基二苯并噻吩参数和Ts/(Ts+Tm)成熟度参数显示和田河轻质油处于高成熟阶段(凝析油阶段),烷基萘类成熟度参数、C29甾烷20S/(20S+20R)和C29甾烷ββ/(αα+ββ)显示尚未进入生烃高峰期。轻烃等参数显示原油高成熟与原油密度等物理性质一致,烷基萘类成熟度参数成熟度偏低可能与原油存在轻微生物降解有关,甾烷成熟度参数偏低是演化达到平衡终点后翻转所致。综合成熟度参数认为,和田河气田轻质原油处于成熟末期-高成熟阶段。与该地区典型的烃源岩样品成熟度对比,推断轻质原油与天然气同源,主要来自寒武系烃源岩。甾萜类生物标志物油-源对比分析支持该结论。 | 崔景伟 王铁冠 胡健 李美俊 | 2013 | 石油与天然气地质2013，34，1： | 18 |
| 2 | Oil filling history of the Bashituo Oilfield in the Markit Slope,SW Tarim Basin,China显示文摘The Markit Slope is an important area for the petroleum exploration in the Tarim Basin. Elucidation of the oil filling history of discovered oilfields has great significance for recognizing the accumulation processes of the whole region. Using molecular geochemistry, fluid inclusion techniques and basin modeling, we studied the oil filling process of the Bashituo Oilfield that is located in the west of the Markit Slope. The molecular migration indexes, such as the methyldibenzothiophene ratio (4-/1-MDBT), trimethylnaphthalene ratio (TMNr) and pyrrolic nitrogen compounds content, decrease from west to east, indicating that the charging direction and migration pathways are from west to east. Lithological analysis and homogenization temperatures of saline fluid inclusions accompanied with oil fluid inclusions suggest that two charging periods occurred in the Devonian oil reservoir. Combining the burial history and heating history of well BT4, Basinmod 1D software modeling shows the two oil filling periods are from 290 Ma to 285 Ma and from 10 Ma to 4 Ma, respectively, and later oil filling dominates. This study may be helpful to understand the accumulation process and provide useful references for oil and gas exploration in the Markit Slope. | Cui Jingwei Wang Tieguan Li Meijun Ou Guangxi Geng Feng Hu Jian | 2013 | Petroleum Science2013，10，1： | 11 |
| 3 | 塔西南地区原油轻烃特征及成因类型显示文摘塔西南地区是塔里木盆地石油勘探的后备区,整体考虑区域内已发现轻质原油的轻烃地球化学特征,对确定区域内原油成因类型和成藏过程具有重要意义。利用配置PONA毛细管柱的GC对区域内22件原油进行C6—C13轻烃族组成、族组分比值、MCyC6/nC7和m-xylene/(m-xylene+nC8+nC9)分析。结果表明,塔西南地区原油可划分为巴什托轻质油族群、和田河轻质油族群和柯克亚轻质油族群3个族群。族群划分结果显示原油存在3套烃源岩,部分原油存在混源特征,轻烃结果受原油芳烃和碳同位素分析支持。 | 崔景伟 王铁冠 李美俊 耿峰 唐友军 胡健 | 2015 | 天然气地球科学2015，26，7： | 4 |
| 4 | Identification and geochemical significance of polarized macromolecular compounds in lacustrine and marine oils显示文摘Polarized macromolecular compounds in typical lacustrine and marine shale oils collected from the Ordos Basin and Tarim Basin of China were analyzed by FT-ICR-MS. Maturity was taken into consideration by diagenesis physical simulation experiments on shale oils, which had been collected at various temperature and pressure stages. The results showed that similar components existed in non-hydrocarbon and asphaltenes and the main peak compound classes of N1 and O2 were potential parameters for identifying typical marine oil and lacustrine oil in China. Nitrogen compounds/(nitrogen compounds and oxygen compounds), such as N1/(O2+N1), N1/(O3+N1), N1/(N1O1+N1O2) are the maturity indicators, which are related with C-N and C-O bond energy. Differences in molecular components and weights between marine and lacustrine oils are the effective index to identify source maturity and sedimentary environment. | CUI Jingwei ZHU Rukai HU Jian | 2014 | Chinese Journal Of Geochemistry2014，33，4： | 2 |
